FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing azafullerene C48N12, where a suspension of β-naphthol in water is nitrated with nitric acid with concentration of 5-6% at temperature of 96-98°C on a water bath for 2-2.5 hours in the presence of acetic acid in amount of 25-30 ml/l with respect to glacial acetic acid; the formed reaction mass is filtered, ground, washed with water from nitric acid to a neutral medium and dried at temperature of 70-80°C; to obtain azafullerene C48N12 with purity of 96-98%, selective washing is carried out in a Soxhlet apparatus, after which the azafullerene is recrystallised, washed and dried at temperature of 70-80°C.
EFFECT: invention enables to obtain said azafullerene via low-temperature liquid-phase synthesis.
